Fire does not show in final render
Were you hoping for something more like the following (frame 8)?



If you were, you needed to change the material, Material, from a Transparent BSDF to the following node setup. This is pulled from the Vfx Blender's YouTube video, How to kick a Fireball (blender tutorial) [HD] part 1.

As I understand it, it uses the Attribute nodes to determine what part of the cube's volume is smoke and what is fire. The ColorRamp obviously colors the fire, and the Math > Multiply node set to 9.000 determines how transparent the fire is (0 being clear). The Math > Multiply node set to 7.500 determines how transparent the smoke is (0 being clear).



Here is the adjusted .blend file (w/o textures because they didn't come through Google Drive):
